W-NVR K8210-3WS no detect HDD

Good afternoon,

I updated my W-NVR K810-3WS to firmware version 3.2.4.9M, and since the restart, it does not detect my hard disk drive (HDD). I have tried with a new disk, but it also does not detect the disk. I have attempted a factory reset, but it still does not recognize the hard drive. I have checked for defective sectors, FAT, and MBR, and the disk is in perfect condition, so I believe the issue is due to the firmware update. What can I do?

Is there any way to obtain a previous firmware version?

Thank you.

And the relation with Home Assistant is… ?
